hey guys,

I have ran into a snag, I just got my new motor from a friends RUNNING car, it came with the motor, trans, upper and lower harnesses, coil, wires, literally everything to get it going. well I swapped it into the car and then all it would do is turn over, I later realized my fuel pump wasn't primping so I pulled it out and had a look, it was solid rust. I then emptied the gas tank and cleaned it out trying to remove as much rust as possible. I then put fresh gas in with a new pump. that solved the pump not primping. next I discovered my fuel lines were backwards so I switched them around. now my rail is receiving fuel. Next I tested my injectors and they all work when the clips are removed and 12v is put directly to them, I can even get the car running this way and it stays running till the fuel is burnt. I then tested the clips for power and they are all receiving power. After that I went looking for grounds. I cleaned off the one on the coil, the one on the fire wall that attaches to the head on the driver side, the two that are on the frond of the head infront of the #1 injector, the one by the temperature sensor, the one that is on the intake manifold for the negative battery terminal, the one that is attached to the battery tray again for the negative terminal, and lastly the one that is directly under the fuse box panel. I have tested my EGI and EGI pump relays and they both work, my egi fuse is good as is the one above it, I have both a red and a green light on my ecu, and this is my 3rd harness I have tried and 3rd ecu as well... I dont know what else to check. please help...

I don't know what else to check, the only other thing that comes to mind that might possibly affect the fuel getting to the motor is the filter and pressure regulator, but it seems you know a lot more than me so I'm just mentioning those in case you happen to draw a blank

thanks for trying vegass13 its more then any of the others who have looked at the thread and left no feedback, but my fuel filter is new and I know the regulator is in good working order as the day I ripped out the motor from my friends car it ran and drove fine.

True forgot about that...have you tried taking the fuel line off from the rail and crank it just to be absolutely sure the pump is sending fuel?
